CPTIA Dumps with Practice Exam Questions Answers

In the trust model described, where trust between two organizations depends on the degree and quality of evidence provided by the first organization, the model in use is 'Validated Trust.' This model relies on the validation of evidence or credentials presented by one party to another to establish trust. The validation process assesses the credibility, reliability, and relevance of the information shared, forming the basis of the trust relationship between the sharing partners. This approach is common in threat intelligence sharing where the accuracy and reliability of shared information are critical.References:

In Wireshark, the filtericmp.type==8is used to detect ping sweep attempts. ICMP type 8 messages are echo requests, which are used in ping operations to check the availability of a network device. A ping sweep involves sending ICMP echo requests to multiple addresses to discover active devices on a network. By filtering for ICMP type 8 messages in Wireshark, Bran can identify these echo requests, helping to pinpoint ping sweep activities on the network.

References:Wireshark, as a network protocol analyzer, is frequently discussed in the CREST CPTIA program, with particular emphasis on its utility in detecting network reconnaissance activities like ping sweeps through specific filter usage.

Fast-Flux DNS is a technique used by attackers to hide phishing and malware distribution sites behind an ever-changing network of compromised hosts acting as proxies. It involves rapidly changing the association of domain names with multiple IP addresses, making the detection and shutdown of malicious sites more difficult. This technique contrasts with DNS zone transfers, which involve the replication of DNS data across DNS servers, or Dynamic DNS, which typically involves the automatic updating of DNS records for dynamic IP addresses, but not necessarily for malicious purposes. DNS interrogation involves querying DNS servers to retrieve information about domain names, but it does not involve hiding malicious content. Fast-Flux DNS specifically refers to the rapid changes in DNS records to obfuscate the source of the malicious activity, aligning with the scenario described.References:

ISO/IEC 27002 is a standard that provides best practice recommendations on information security controls for use by those responsible for initiating, implementing, or maintaining information security management systems (ISMSs). It covers areas such as risk assessment, human resource security, operational security, and communications security, among others, providing a framework for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving an ISMS. ISO/IEC 27035 pertains to information security incident management, PCI DSS (Payment Card Industry Data Security Standard) deals with the security of cardholder data, and RFC 2196 is a guide for computer security incident response teams (CSIRTs), not a standard for implementing ISMSs.References:The CREST CPTIA curriculum includes the study of various standards and frameworks that support information security management and governance, including ISO/IEC 27002, highlighting its role in guiding organizations in implementing effective security controls.

The analyst used Open Source Intelligence (OSINT) to gather information from publicly available sources. OSINT involves collecting and analyzing information from publicly accessible sources to produce actionable intelligence. This can include media reports, public government data, professional and academic publications, and information available on the internet. OSINT is widely used for national security, law enforcement, and business intelligence purposes, providing a rich source of information for making informed decisions and understanding the threat landscape.References:
